Corrected entry: In "The One With The Secret Closet," the whole show is about Monica's secret closet (the one near the bathroom), why she keeps the door locked and how Chandler wants to find out what's in there. However, in "The One With The Dozen Lasagnas," the door is open and the closet reveals nothing more than clothes and other regular stuff you put in a closet. Also in the one where Phoebe and Rachel are looking for Christmas presents Rachel says she'll go and check the back closet, the one next to the bathroom.

Correction:Chandler says "since I've lived here, I've never seen the inside of that closet" or something along those lines. Monica had plenty of time to clutter up that closet, without Chandler ever having to see it.

When Rachel finds out that Ross and Julie are getting a cat, watch Rachel's neck. When she says "together?" she's not wearing a necklace; cut to Ross and Julie for a fraction of a second, then when it cuts back to Rachel saying "both of you?" she's suddenly wearing a necklace. It then disappears again when she says "isn't that just lovely?" hanging off the side of the tray she's holding.
